Of course, the old bank will continue to publish papers, engage in scientific research, and improve its academic status.

This era is not the year 2020 in reality, and there is a huge gap between China and Western countries in various fields such as economy, science and technology, and military.

When facing foreigners, especially in Western countries, Chinese people will not feel inferiority complex and admiration.

The moon in a foreign country is round, which is a true portrayal of this era.

Once Pang Xuelin completes the conjecture proof of the seven difficult problems of the millennium and publishes papers in the four major journals, the effects and topics will be sensational.

In terms of attention, it will even surpass the real world, and it is not impossible to be made into a benchmark for China's academic community.

At that time, with Pang Xuelin's academic status, there will be a lot of room for maneuver in the field of education.

However, which results will be selected for publication next?

Pang Xuelin buried his head in contemplation.

Ponzi geometry, ABC conjecture, and solving nonlinear partial differential equations were all excluded by Pang Xuelin.

The basis of these three achievements is Ponzi geometry, and the basis of Ponzi geometry is far abelian geometry.

At present, Grothendieck has only been able to figure out far-abelian geometry for a long time, and the research on far-abelian geometry in the international mathematical community is still quite shallow, so if you want the international mathematical community to accept Ponzi geometry based on far-abelian geometry, you don't know if you have to wait until the year of the monkey.

Since several papers related to Ponzi geometry are not suitable, the only ones to choose from are the BSD conjecture, the Fermat conjecture and the Poincaré conjecture.

Among the three, Pang Xuelin thought about it and finally chose the Fermat conjecture.

Before the Clay Institute came up with the so-called seven mathematical problems of the millennium, the Fermat conjecture, the four-color conjecture, and the Goldbach conjecture were called the world's three major mathematical problems.

Compared with the other two, the Fermat conjecture, which has a history of more than 300 years, is even more famous, and its status in the mathematical community is not much inferior.

In the real world, Fermat's conjecture was proved by Andrew Wiles in 1994, and now Pang Xuelin still has enough time.

In addition, as a special corollary of the ABC conjecture, Pang Xuelin wants to prove the Fermat conjecture with the help of some relevant ideas of Ponzi geometry, and the proof method is much more concise than Andrew Wiles's proof method.

"Teacher Pang, what are you doing sitting here? It's snowing and you still have a fever, so go back to the house and lie down! ”

A Qing's voice sounded in Pang Xuelin's ears.

Pang Xuelin raised his head, only to find that at some point, snowflakes began to float in the sky.

Pang Xuelin suddenly turned his head, looked at Ah Qing and said, "Ah Qing, how long has it been since you eaten meat?" ”

"Huh?"

Ah Qing was stunned, swallowed his saliva unconsciously, and said, "Pang ...... Mr. Pang, it's been about a month! ”

Pang Xuelin said with a smile: "In two days, the teacher will give you stewed pork to eat, okay, you go to self-study, and help the teacher manage the group of bear children." ”

"Oh!"

Ah Qing's eyes lit up, turned his head and ran in the direction of the classroom, shouting as he ran: "You all listen, Teacher Pang said, if anyone is quiet in the classroom and studies hard, Teacher Pang will give him stewed meat to eat, and if anyone is noisy and noisy, let alone pork, I won't leave you a single oil residue!" ”

In the classroom, the faint noise fell silent in an instant.

Pang Xuelin couldn't help but shake his head, smiled dumbly, and then dragged his somewhat heavy body towards the dormitory.

In the afternoon, Pang Xuelin slept again, and when he woke up, it was already dark.

There was a faint sound of firewood crackling and the smell of brown rice in the hall.

Pang Xuelin got up from the bed, touched his head, and felt that the high fever on his body had completely faded.

Through the window, you can see that the sky outside has become dark, the sky is overcast, the snow has stopped, and the distant mountains are covered in a layer of silver.

When he came to the hall, Ah Qing was burning the fire, and when he saw Pang Xuelin coming out, Ah Qing said: "Teacher Pang, we eat rice at night and shredded radish left over at noon, and I also made an egg custard, steamed for you to replenish your body." ”

Pang Xuelin was a little puzzled and said, "Ah Qing, why don't we stew at noon?" ”

Ah Qing pouted and said, "Make egg custard at noon, you will definitely not eat a bite yourself, and you will have to share it with others." ”

"You little slippery!"

Pang Xuelin shook his head helplessly.

……

Twenty minutes later, the two of them had dinner.

A plate of shredded radish, a bowl of egg custard, and rice is dinner for two.

Pang Xuelin ate a few bites and found that Ah Qing had eaten some shredded radishes, but he didn't touch a bite of the egg custard.

Pang Xuelin frowned, snatched the rice bowl from Ah Qing's hand, and used a soup spoon to put half of the egg custard into Ah Qing's rice.

"Teacher Pang, this is a ...... for your body"

Pang Xuelin pushed the bowl in front of Ah Qing and said, "It's delicious, don't give me a bite left!" ”

"Oh!"

Ah Qing lowered her head and took the rice bite by bite, but her eyes were slightly red.

Pang Xuelin sighed, a little helpless.

The profession he inherited is currently 120 yuan per month, all year round, plus various subsidies, about 1,500.

In 1992, it would have been difficult to support himself with this amount of money if he was placed in the city, but in this remote mountain village, he should have belonged to the high-income class.

In addition, there is still an acre of paddy field and half an acre of dry land at home, so he will not be able to afford to eat meat.

But who let his adoptive father Hu Wenbin, in order to let the villagers send their children to school, proposed that as long as the children come to school, the school can take care of the meals at noon.

At this time, the education department had not yet proposed a free lunch plan, and Hu Wenbin's free lunch had no way to get financial allocation from the township.

He can only deduct it from his own salary.

Half-sized, eat poor old man.

There are more than a dozen mouths at noon, and the expenses of a month are suddenly larger, plus he has to buy all kinds of stationery and books for the children, Pang Xuelin's monthly salary is also a little stretched.

But the matter has come to this, and Pang Xuelin has no good way.

The measures to throttle money have been taken to the extreme, and if he continues to save money, he and his children will have to go hungry, so the next step is to find a way to open source.

After dinner, Pang Xuelin and A Qing cleaned up the dishes and chopsticks together.

It was already completely dark, and the two of them closed the door of the hall, lit another oil lamp, and lit a charcoal fire, and the room was finally a little warmer.

Ah Qing was doing his homework in front of the oil lamp, while Pang Xuelin took out a pen and paper and began to formally write the proof paper of Fermat's conjecture.

An hour later, after Ah Qing's homework was finished, the little guy came to Pang Xuelin's side with some curiosity, looked at the words on the paper like a book from heaven, and said curiously: "Teacher Pang, what are you writing here?" Pinyin? ”
